我在Spring-boot项目中定义了2个DataSource，我也有2个@Repository。
我的
中有这段代码Application.java
@SpringBootApplication
@EnableJpaRepositories(basePackages = {"com.opes.kyc_adapter.repository.postgresql", "com.opes.kyc_adapter.repository.mysql"})
@EntityScan(basePackages = {"com.opes.kyc_adapter.model.postgresql", "com.opes.kyc_adapter.model.mysql"})
public class Application implements CommandLineRunner {
@Autowired
private MessageRepositoryMySQL repositoryMySQL;
@Autowired
private MessageRepositoryPostgreSQL repositoryPostgreSQL;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
public void run(String... arg0) throws Exception {
for (int i = 0; i < 5; i++){
repositoryMySQL.save(new MessageOriginal("My post number #" + (i+1)));
repositoryPostgreSQL.save(new MessageExtracted("My post number #" + (i+1), "User #" + (i+1)));
}
}
}
如你所见，我有2个@Repository
每个repo应该将数据添加到不同的DataSource，但两者都添加到MySQL Datasouce。
以下是代码的其余部分：
DataBaseConfigurationMySQL.java

}
@Bean
@DependsOn("jdbcTemplate")

LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
if (persistenceUnitManager != null) {
entityManagerFactoryBean
.setPersistenceUnitManager(persistenceUnitManager);
}
entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
entityManagerFactoryBean.setDataSource(dataSource);
entityManagerFactoryBean.setPackagesToScan("com.opes.kyc_adapter.model.mysql");
entityManagerFactoryBean.getJpaPropertyMap().putAll(jpaPropertyResolver.getSubProperties("properties."));
Map<String, Object> properties = entityManagerFactoryBean.getJpaPropertyMap();
properties.put("hibernate.ejb.naming_strategy", jpaPropertyResolver.getProperty("hibernate.naming-strategy", SpringNamingStrategy.class.getName()));
